A thief stole hundreds of dollars from Peter Leach's campervan, but left no fingerprints - because the thief has no fingers.

Mr Leach, a visitor from Glasgow, Scotland, stopped at Arthur's Pass on Wednesday to take in the views at a rest area along State Highway 73.

He left the windows down as he snapped photos of the scenery, including one of an unusual bird on the ground near his vehicle. Little did he know he'd become a target for the local criminal element.

"A Canadian couple walked by and said: 'We've just seen that bird take something out of your campervan'," Mr Leach laughed.

"It took all the money I had. I was left with $40 in my pocket."

The unsuspecting tourist had stashed his travel cash - about NZ$1300 - in a small cloth drawstring bag and left it on the dashboard, where the bird apparently found it while rummaging through other items.

The kea grabbed the bag and made a clean aerial getaway.

Fortunately, Mr Leach had old friends nearby, Paul and Lyn Fisher of Normanby, who lent him cash to tide him over.
